Did you even read the other posts? Like someone above you mentioned, there are lots of ways to capitalize on things you give away. Books: autograph signings or serialized content, or paper books. Music: Concerts, t-shirts, hard copy sales (hard to find pirated Vinyl) even iTunes is turning a profit. None of these suggestions lead to any of the things you said, but giving away digital versions will almost certainly increase sales of your other warez. I know some public speakers who make upwards of $200k per speech, everything else they can give away because they make more than enough off speaking alone.
